Mrs Lugnutty and I just spend an hour or so stitching a new rear window into the new old Miata! It started out windowless, but a trip to JoAnn Fabrics solved that with 1 yard of 20-gauge marine clear vinyl, upholstery thread, and some Billy Mays-endorsed Mighty Mend-It. It's not quite professional upholstery work, but it was our first time. I think it we do it again we'll have it nice and flat and ripple-free. But for $18.23 I am quite pleased.
